The present invention relates to improvements in testing devices forwater systems, and has for an object to provide certain improvementsover my prior Patent No. 1,155,-

" 821, granted October 5,1915.

' 1 It is another object of the invention to provide an improved testingdevice for removable mounting in a pipe joint, whereby the same willfunction to hold the interfitting pipe section in place while the jointmaterial is being packed thereabout.

, A further object of the invention is to provide an improved testingdevice which is removably mounted within the pipe joint and I acts todrain the same.

With the foregoing and other objects in view, the invention will be morefully described hereinafter and will be more particup V r v nThus,'thetest1ng.plug' hasthfeeffect bothto f inner movement sothat'it'alwaystakesu jg a 7 correct position with respect'to-t'he packing a,

In this packing box is adapted to be re-V ceived any appropriate packingmaterial, for; instance, the'lead packing 9v and the waste or fiber 10.A plate 11 is employed to holdtlie packing material in place, such platebeing secured in place as by the use of bolts or other fastenin'gs 12,which pass through the plate 11, and out-turned flanges 13 upon the pipejoint. i Pr ferably, the plate 11 is shouldered or'fianged, asindicated'at 14, to take up a proper position and to properly center theinterfittingpipe section 15.
